Hi all,

I have a table having 20 fields & 10 rows with one field as primary key
say rollNo.
I want to copy a row of the table to the table itself with a new
rollNo.

Is there a simple way out or i have to take the row in a dataset & then
modify the rollno column of the dataset with the new value & after that
write a insert query like:
insert into mytable values(dataset.Tables[0].Rows[0]["RollNo"],
dataset.Tables[0].Rows[0]["RollNo"],.....& so on).
The approach that i have written is a very cumbersome one..
also think of a table having 80 - 100 rows...unfortunately i have one
:-(

Kindly Help
Warm Regards
Sumit

easiest way is to create a data adapter pointed at your table. Fill a
dataset using the data adapter, filtered as best you can to get as few rows
as possible.

Find the row you want to duplicate.

Then, using the rows and columns collections of the dataset, copy the value
of the old row to the new one. Catch and change the primary key column.

Then use the data adapter to write the updated dataset back, which will do
the complex insert statement for you.

The amount of code should be less than about 50 lines for a generic solution
you can reuse.
